i looked into it,uninstalled all c++ runtime librarys on my seperate windows drive (i have 2 ,1 to check and other to program) ...now it kept working so i dont know if theres files hidden somewhere (c++ runtime files),BUT i have to say that this also occurs when the navmesh plugin.dll is NOT INSIDE OF GAMESTUDIO\PLUGINS folder so without being nasty i have to ask did you copy the navmesh plugin.dll found inside ""navmesh plugin for acknex.zip"" the first one in the list /or inside the release folder,did you copy that into your gamestudio\plugins folder ?
